'GiARBIDE-DISCHARGING MEANS.

Application fiie'a October 3, 1921. Serial No. 505,112.

To all toil/omit may} concern)" w Be it known that I, NATHANIEL H. HALE, a citizen of theUnited States, residing at Stone, in the coiirity ofPike and State of Kentucky, have invented certain new and useful Improvements in Qarbide-Dis'charg ingll iachinesof which-the following .is a all. clear, and exact descriptiori'thereof. I

My invention relates to. carbidedischarging machines, and one of the: objects of my invention is to provide a machine of this character whichwill discharge carbide in accurately measured quantities. n j I Another purpose ofmy invention is to provide carbide discharging machine which eliminates the necessity for any special container, the ordinary carbidev shipping drum being applied directly to'the ,dis-

charging machine, and thus there is no transfer of thecarbide. I

, Another purpose otmy invention is to provide a machine of this character wherein the desired amount of carbide maybe quicklyv dispensed without the necessity ofthe clerks hands coming into contact with the carbide.

Another advantageousresultof my invention is that. it prevents the escape into the storeroom of the disagreeable carbide fumes.

Another advantage of my invention residesin the great saving of time which is accomplished. I f

Still another advantage, resulting from the use of my invention is that the carbide is maintained in a better condition, due to the fact that it isnot necessary ,to be continually removing and replacingthe cover, thereby admitting air and consequently slacking the carbide to some extent.

Other advantages of come apparent as the description proceeds.

In the present practice-of selling carbide for miners lamps andsfor similar purposes, it is necessary every time there is a sale, for the clerkto remove the cover from the carbide drum, scoop out and weigh the carbide, and then secure the cover in place again. This takes much time, andbesides that the storeroom becomes filled with the disagreeable carbide fumes; and air is admitted to the carbide :drum resulting in some slacking of the .carbide. It is also necessary for the clerk to take the time to. wash his hands each time he handles the carbide.

All of the above notedinconvenlefices and others are everoeme by the use of: my in'ven;

my invention] will betion, which I will now describe in detail, retere'nce being had to the accompanying draw ings, inwhich,

Figure 1 is a perspective view of ratus completely assembled.

Figure 2 is a transverse sectional view of the discharging apparatus, the table I and the appadrum being broken ofi'.

Figure'3' is a longitudinal sectional view of the discharging apparatus, which is shown as removed fromthe drum and table.

Figure 4 is a plan view of the discharging apparatus from the'under side.

Figure 5 is a detail perspective view of the measuring cup.

Figure 6 is a fragmentary view showing the stop arrangement; and,

Figure 7 is a detail view of the'table, with the drum and discharging apparatus removed.

Referring to the drawings more in detail, numeral 1 indicates the ordinary, carbide shipping drum, and in the present invention this drum is applied directly to the discharging and measuring mechanism. Numeral 2 refers to the body of the discharging apparatus, and cast integral with this body is the supporting flange 3, and the discharging nozzle 4. The body member is closedat one end 5, and is open at the other end, and

- adapted to receive the measuring cup 6.

The measuring cup 6 is provided with an opening 7 which is arranged to. register alt'ernately with the opening 8 in the'body. and with the nozzle 47. The measuring cup is entirely open at one endand is closed at the op posite end 9, and cast on the closed end is a lug .10 forarresting the rotative movement of the cup. The cup is attached to the open ating shaft 11 by a set screw 12, and the shaft is 'journalled in one wall of the body member as indicated by numeral 13. The shaft is provided on its opposite end with any desired formot operating lever 14.

'Twolu'gs 15, adapted to be engaged by the lug 10 on the measuring cup, are cast integral withthe body member.

To. support the apparatus I provide any suitablestand or table having an annular basemember 16 on which the flange 3 rests. the discharging mechanism projecting downwardly through the opening in the table. or stand. An u] 3wardly. projecting flange 17 is provided on the a'nrk' iar base member for. the sax-pa e at firmly holding: the enpportiiia flange 3 and the carbide drum 1. A slot 18 is provided in the annular base member to permit the operating shaft 11 to pass down wardly through the table, and if desired a stirrup may be provided to assist in supporting the operatin shaitt after the mechanism is assembled on are table. T

I will now describe the means for securing the discharge mechanism to the car bide drum.

Screw-threaded hook-shaped members 19 pass through the supporting flanges 3, and the hooks are adapted to engage over the inwardly projecting collar 20 provided on all carbide drums. A gasket 21 is employed between the supporting flange 3 and the carbide drum for the purpose of preventing the admission of air to the drum. Bysetting up on the nuts 22 the drum, the gasket, and the discharge mechanism, are bound tightly together.

To remove the drum it is only necessary to loosen the nuts, push the hook members upwardly and rotate them a halt turn out of engagement with the collar on the drum. Indicating fingers are provided on the hook-shaped members for the purpose of showing the position of the hooks and thus facilitate the mounting and removal or" the drum.

The operation of the apparatus is obvious, Assuming the parts to be in the position shown in Fig. 2, the carbide will flow from the drum into the measuring cup and fill the latter. Now when it is desired to dispense the carbide it is only necessary to grasp the operating lever and rotate the cup until the lug 10 engages the lug 15. The position of the measuring cup is now reversed, and the opening '7 will register with the discharge nozzle, thereby permitting the carbide to flow into the bag which is held around the discharge nozzle. The cup is now rotated in the opposite direction until the lug 10 engages the other lug 15, when the opening 7 registers with the o ing 8, thereby allowing the carbide to fill the measuring cup. Of course the cup will. be made of such size to discharge the desired amount of carbide at each operation of the apparatus.

From the foregoing description it will be clear that l have devised an inexpensive apparatus which will quickly discharge accurately measured amounts of the material: that it is unnecessary to employ any special container with the apparatus as the carbide shipping drum is applied directly to the discha "ring apparatus, and by so employing the drum it becomes unnecessary to handle the carbide at all; that air is prevented from entering the carbide drum at all tii'nes; and that as the bag covers the nozzle when carbide is being dispensed, the disagreeable 2. measuring and discharo'i including a body member, a incasur'ng cup rotatively mounted in the body member, supporting flange provided on the body ,7 a )paratus member, a container associated with the body member, said container comprising a conventional carbide shipping drum, and means for securing the container to the body member, said securing means comprising hook-shaped members passing through the supporting flange and engaging over the inwardly extending collar of the carbide drum. i

3. A measurin and disrha ging apparatus including a body member, a measuring cup rotatively mounted in the body member, a

supporting tlange provided on the body member, a container associated with the body n'iember, said container comprising a mmrentio r shipping drum, means tor securing ll-1' (5 "nor to the body member, said seruring means comprising hook-shaped members passing through the supporting flange and engaging over the inwardly extending collar of the carbide drum, and means on said hook-shaped members for indicatingwhether said members a e in or out eng gement with said collar.

l, A measuring and disrlr apparati't-a including a body member, said member bein open at one end. 2111(1 closed the other end, a measuring cup rotatively mounted in said. body. member, said cup being open one end and closed atthe otherend, a supporting flange provided on the body memher. a table, said table having an annular base member for receiving said supporting flange, a container ssociated with the body member, said container being a. conventional, carbide shipping drum, means for securing said container to the body member, said means comprising hook-shaped n'iembers passing through the supporting flange and ei'igaging over the inwardly extending collar of the caroide drum, and means for indicating the angular position of the h.ookshaped members.
